Figure 1

Light microscope images of the novel MTB of the Gammaproteobacteria. (a, c) Differential interface contrast (DIC) light micrographs of north-seeking cells of strains BW-2 and SS-5, respectively, at the edge of a ‘hanging drop' in a magnetic field. (b) High-magnification DIC micrograph of cells of BW-2 showing the numerous, refractile, intracellular, sulfur-rich globules. (d) High-magnification DIC micrograph of very-long cells of strain SS-5 common in older cultures. (e) Fluorescence microscope image of the same SS-5 cells shown in (d) but stained with 4′,6-diamidino-2-phenylindole (DAPI) to show the numerous nucleoids present in very-long cells.
